a.Jack up the front of the mowing deck about one foot and block it in that position.

b.Make sure the blade clutch is disengaged.

c.Remove the deck cover.

d.Remove the drive belts. (See 3. Changing Blade Drive Belts.)

e.Remove the cutter blade. (See 2. Chang- ing a Blade.)

f.Using a wrench or socket rachet remove four hex nuts, and the four hex head cap screws. Remove the spindle assembly.

B.Hydraulic Oil

B.Hydraulic Oil WARNING:

Never overfill the hydraulic units. Damage can occur if the oil level is not within the proper operating range.

Note: When adding hydraulic oil, do so in

small quantities and recheck the oil level before adding more. It is important that you do not overfill the reservoir.

d.Remove the hydraulic fill cap and check the level. The correct level is up to the low- est hole of the oil tank fill neck.

e.Pour hydraulic oil into the reservoir up to the lowest hole in the oil tank fill neck, if necessary.

2.Draining Hydraulic Oil

Used hydraulic oil must be disposed of properly. Do not pour it down a drain or sewer, or dump it on open land, this creates an environmental hazard. Please be aware of the environment when disposing of used oil.

a.Place the Mower on a level surface and engage the parking brake.

b.Stop the engine and remove the key from the ignition switch.

c.Remove the mower deck. See Mower Deck on page 13.

d.Raise the seat forward to expose the hydraulic oil fill point.

e.Clean the area around the hydraulic fill oil cap.

f.Remove hydraulic fill oil cap.

g.Place a suitable container (at least 2 gal- lon) under the hydraulic reservoir and filter.

h.Remove the hydraulic filter to allow hydrau- lic oil to drain. Remove the drain plug from the bottom of the hydraulic oil tank to drain. Replace the plug.

i.Place a small pan under the skid plate. Remove fill oil cap from hydraulic reservoir for faster drainage. Remove nut caps and
